In this paper we analyse the problem of incorporating prior knowledge when learning univariate MoTBFs. We consider scenarios where the prior knowledge is expressed as an MoTBF that is combined with another MoTBF density estimated from the available data. An important property, from the point of view of inference in hybrid Bayesian networks, is that the density yielded after the combination is again an MoTBF. We show the performance of the proposed method in a series of experiments with simulated data. The experiments suggest that the incorporation of prior knowledge improves the estimations, especially with scarce data.<\/jats:p>","DOI":"10.3233\/978-1-61499-330-8-95","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:26:53Z","timestamp":1740133613000},"source":"Crossref","is-referenced-by-count":0,"title":["Incorporating Prior Knowledge when Learning Mixtures of Truncated Basis Functions from Data"],"prefix":"10.3233","author":[{"family":"Fern&aacute;ndez Antonio","sequence":"additional","affiliation":[]},{"family":"P&eacute;rez-Bernab&eacute; Inmaculada","sequence":"additional","affiliation":[]},{"family":"Rum&iacute; Rafael","sequence":"additional","affiliation":[]},{"family":"Salmer&oacute;n Antonio","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Twelfth Scandinavian Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:32:29Z","timestamp":1740133949000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=257&spage=95"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-330-8-95","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2013]]}}}
